PATEN BUNG-BUSH WRENCH.

SPECIFICATION forming part of Letters Patent No. 291,193, dated January1, H84.

A1 p'ieation filed June 30, 1883. (No model.)

To all whom it may concern:-

Be it known that I, SAMUEL H. JENKINS,

of the city, county, and State of New York,

have invented certain new and useful Improvements in Bung-Bush Wrenches,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

My invention relates especially to wrenches employed for insertingbung-bushings such as described by me in an application filed April 23,1883, and has for its object the provision of a wrench whereby thebushing may be easily and quickly screwed into the barrel.

My improved bush-wrench consists, essentially, of a metallic shank, oneextremity of which bears one or more eccentric projections adapted andarranged to take against the shoulder or shoulders formed in the bushwhile screwing the same into the barrel. The extremity of the wrenchwhereon said projection or projections are formed is of such shape as tofit the interior of the bush. By use of a wrench of this constructionthere is no outward pressure such as is necessarily exerted by thewrenches heretofore in use; but as the pressure is exerted in the lineof movement of the bush in placing it in position, danger of breakingthe same while screwing into the barrel is obviated. Upon the extremityof the shank, opposite to the wrench, is formed a tap, adapted andarranged to out a thread upon the edge of the hole wherein the bush isto be inserted, and to sink the beveled flange at the outer extremity ofthe bush flush with the surface of the barrel; If desired, the entterfor forming the countersink may be located upon the shoulder of thewrench, just above the eccentric projection. By cutting the thread inthe barrel, the same being smaller than that upon the bush, said bushisinserted with greater facility than could be done without such thread,while by countersinking the flange at the exterior of the barrel thereis little danger of breaking the bush while driving home the woodenbung.

In the drawings, Figure 1 is a longitudinal elevation of my improvedbung-bush wrench. Fig. 2 is a cross sectional View thereof at line x xof Fig. 1, and Fig. 3 is a like view at line Like letters of reference,wherever they occur, indicate corresponding parts in all the figures.

E is the shank of the wrench, formed of suitable material, -and providedwith eccentric projectionsF, corresponding to the shoulders formed inthe bung-bush.

G is a tap located upon the extremity of the shank, opposite to thewrench, designed for cutting a thread in the edge of the hole into whichthe bush is to be screwed.

H is a cutter or knife at the inner end of the thread, or at the shankabove the eccentric projections F, orin both positions, adapted andarranged to form a countersink for the shoulder upon the bush.

I is the lever-handle, by which the tap and wrench are manipulated.

Having now fully described my invention, what I claim as new therein,and desire to secure by Letters Patent, is

1. A bung-bush wrench consisting of a shank, whereon are located one ormore eccentric projections, substantially as shown and described.

2. A metal shank having one or more eccentric projections at oneextremity, forming a wrench, and a screw-cutting tap at the other, ahandle beingsecured to said shank, and adapted and arranged to operateeither wrench or tap, substantially as shown and described.

3. In a bung-bush wrench of the character herein specified, shank E,bearing one or more eccentric projections, F, tap G, cutter or cuttersH, and lever-handle I, the whole combined and arranged to operatesubstantially as shown and described.

In testimony that I claim the foregoing I 90 have hereunto set my handin the presence of two witnesses. SAMUEL H. JENKINS.
